Does Kate Somerville Line Release Under Eye Repair Cream Work?

  • Moderate moisturizing. It has a moisturizing rating of 5.0 out of 10.

Key Benefits of Kate Somerville Line Release Under Eye Repair Cream

 
These are the key benefits you can expect from using Kate Somerville Line Release Under Eye Repair Cream:
 

Lightweight Moisturizer Well-Suited for Combination and Oily Skin

According to CreamScan analysis, Kate Somerville Line Release Under Eye Repair Cream is quite moisturizing, with a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive? Rather humectant. It has a high humectancy of 6.3 out of 10, primarily due to the substantial concentration of Glycerin (est. ≈3.0%), and a moderate occlusivity of 3.6 out of 10, mainly due to the significant content of Phenyl Trimethicone (est. ≈4.0%).

This type of moisturizer is well-suited for people with combination and oily skin who want significant hydration in a relatively lightweight, non-greasy formula. It combines a substantial amount of humectants with a limited amount of occlusive to enhance moisturizing efficacy without feeling too heavy.

This product may also be an option for people with normal skin who prefer fast-absorbing textures, as it balances significant moisturizing potential with a relatively lightweight texture.

A Humectant Enhancement for Any Skincare Routine

But it’s not limited to combination and oily skin - such a humectant enhancement will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer. This type of formulation is typically used in serums, where a light, fast-absorbing texture is key.

Please refer to the Ratings section below for details of the moisturizing rating calculation.

Please note that this is not a complete list of benefits. We are in the process of enhancing our AI model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.

Things to Be Aware Of: Kate Somerville Line Release Under Eye Repair Cream

 
CreamScan AI identified a few things to consider before adding Kate Somerville Line Release Under Eye Repair Cream to your skincare routine:
 

Questionable anti-wrinkle efficacy

If one of your main reasons for choosing Kate Somerville Line Release Under Eye Repair Cream is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently has a zero anti-wrinkle rating.

It contains some ingredients often marketed as effective in reducing wrinkles, specifically Acetyl Hexapeptide-8, Palmitoyl Hexapeptide-12, Palmitoyl Tripeptide-1, Palmitoyl Tetrapeptide-7, Ascorbyl Palmitate, Retinyl Palmitate, and Dipeptide Diaminobutyroyl Benzylamide Diacetate. However, the studies supporting the anti-wrinkle claims of these ingredients provide insufficient evidence of efficacy according to CreamScan Research Evaluation Standards. 

While this does not categorically exclude the possibility that these ingredients may reduce wrinkles, their efficacy is not supported by convincing, vehicle-controlled, double-blind clinical studies - at least none that were accessible to the CreamScan team at the time of publication.

Therefore, these ingredients do not generate the anti-wrinkle rating.

Moisturizers, when used regularly, are proven to prevent wrinkle formation and even reduce existing wrinkles. Therefore, this product, like any other moisturizer, can deliver some anti-wrinkle effects through its moisturizing action.

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.

Ethylhexylglycerin
Est. %0.3
Function
Origin
EthylhexylglycerinA preservative booster derived from glycerin. It is commonly paired with other preservatives to improve their efficacy. Ethylhexylglycerin is also a humectant due to its chemical base of glycerin.
Caprylyl Glycol
Est. %0.3
Function
Origin

Hexylene Glycol
Est. %0.3
Function
Origin
Hexylene GlycolA multifunctional ingredient that is best known for its use as a solvent. It can dissolve both water-based ingredients and oils. For this reason, it can also function as an emulsifier, allowing oil and water ingredients to mix and remain stable.
Dipeptide Diaminobutyroyl Benzylamide Diacetate
Est. %0.3
Function
Origin
Dipeptide Diaminobutyroyl Benzylamide DiacetateA synthetically made peptide similar to the proteins in viper venom. Similarly to Botox, it works by inhibiting contractions of mimic muscles, thereby offering a short-term reduction in mimic wrinkles.
Hydrogenated Lecithin
Est. %0.3
Function
Origin

Superoxide Dismutase
Est. %0.3
Function
Origin
Superoxide Dismutase
Xanthan Gum
Est. %0.3
Function
Origin

Lecithin
Est. %0.3
Function
Origin
LecithinA humectant, emollient, and emulsifier best suited for water-in-oil emulsions. Lecithin can come from sunflowers, soy, and eggs. The downside to lecithin is that it causes an extra burden on the formula’s preservative because it is nutritious.
